Dust Storm over the Red Sea
Title Dust Storm over the Red Sea
Description A dust storm swept over the Red Sea on June 21, 2005. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard the Aqua [ http://www.aqua.nasa.gov/ ] satellite captured this image the same day. Dust obscured the satellite?s view of the Red Sea and the neighboring countries: Sudan, Eritrea, and Ethiopia on the west, and Saudi Arabia and Yemen on the East. Most of Earth?s dust storms arise in a few regions, including the Sahara and the Middle East. As desertification increases, dust storms are likely to follow. The Millennium Ecosystem Assessment has just released its Desertification Synthesis [ http://www.millenniumassessment.org/en/index.aspx ]. The report predicts that the planet?s dry regions will spread as the land surface responds to increased human pressure from poor crop and soil management and irrigation misuse.

Dust Storm over the Red Sea
Title Dust Storm over the Red Sea
Description The dust plume [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13665 ] that blew off the coast of Sudan on June 21, 2006, had petered out a day later. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took this picture on June 22. In this image, the dust plume has dissipated and heads southward over the Red Sea toward the coasts of Eritrea and Yemen. Largely opaque the day before, the dust plume is now thin enough to show the ocean's surface.

Jebel at Tair Eruption
Title Jebel at Tair Eruption
Description Jebel at Tair, a small volcanic island in the Red Sea, erupted late in the day on September 30, 2007, causing several casualties and leaving a number of Yemeni soldiers missing, according to news reports. A Canadian Navy spokesman, who was in the area at the time, described a "giant light show" with spewing lava and an ash cloud reaching hundreds of meters into the air. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ] satellite captured this image of the diminutive volcanic island on October 1, 2007. The haze over the ocean likely results from the eruption, probably a combination of ash and vog—volcanic smog that arises from the mixture of sulfur dioxide, oxygen, and moisture. North of the island appears an area of potentially disturbed water, perhaps caused by ash in the water and/or hot lava leading to water heating and discoloration. Midway between Yemen and Eritrea, Jebel at Tair [ http://www.volcano.si.edu/world/volcano.cfm?vnum=0201-01= ] is a stratovolcano composed of alternating layers of hardened lava, solidified ash, and rocks ejected by previous eruptions. The island is also known as Jabal al-Tair, Jabal al-Tayr, Tair Island, Al-Tair Island, and Jazirat at-Tair. According to The Sydney Morning Herald, Yemen has maintained a military base since 1996 on this volcanic island, which is only about 3 kilometers (1.9 miles) long. Yemen's oil minister stated that earthquakes, registering between 4 and 4.3 in magnitude struck the island on September 30 and likely triggered the eruption.

ASTER
Title ASTER Dunes
Original Caption Released with Image This image of Saudi Arabia shows a great sea of linear dunes in part of the Rub' al Khali, or the Empty Quarter. Acquired on June 25, 2000, the image covers an area 37 kilometers (23 miles) wide and 28 kilometers (17 miles) long in three bands of the reflected visible and infrared wavelength region. The dunes are yellow due to the presence of iron oxide minerals. The inter-dune area is made up of clays and silt and appears blue due to its high reflectance in band 1. The Rub' al Khali is the world's largest continuous sand desert. It covers about 650,000 square kilometers (250,966 square miles) and lies mainly in southern Saudi Arabia, though it does extend into the United Arab Emirates, Oman, and Yemen. One of the world's driest areas, it is uninhabited except for the Bedouin nomads who cross it. The first European to travel through the desert was Bertram Thomas in 1930. Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, California, is the U.S. science team leader, Moshe Pniel of JPL is the project manager. ASTER is the only high-resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface. The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping and monitoring dynamic conditions and temporal change. Examples of applications include monitoring glacial advances and retreats, potentially active volcanoes, thermal pollution, and coral reef degradation, identifying crop stress, determining cloud morphology and physical properties, evaluating wetlands, mapping surface temperature of soils and geology, and measuring surface heat balance.

Title Shaded relief, color as height, Salalah, Oman
Original Caption Released with Image This elevation map shows a part of the southern coast of the Arabian Peninsula including parts of the countries of Oman and Yemen. The narrow coastal plain on the right side of the image includes the city of Salahlah, the second largest city in Oman. Various crops, including coconuts, papayas and bananas, are grown on this plain. The abrupt topography of the coastal mountains wrings moisture from the monsoon, enabling agriculture in the otherwise dry environment of the Arabian Peninsula. These mountains are historically significant as well: Some scholars believe these mountains are the "southern mountains" of the book of Genesis. This image brightness corresponds to shading illumination from the right, while colors show the elevation as measured by the Shuttle Radar Topography Mission. Colors range from green at the lowest elevations to brown at the highest elevations. This image contains about 1400 meters (4600 feet) of total relief. The Arabian Sea is colored blue. The Shuttle Radar Topography Mission (SRTM), launched on February 11, 2000, used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on the Space Shuttle Endeavour in 1994. The mission was designed to collect three-dimensional measurements of the Earth's surface. To collect the 3-D data, engineers added a 60-meter-long (200-foot) mast, an additional C-band imaging antenna and improved tracking and navigation devices. The mission is a cooperative project between the National Aeronautics and Space Administration (NASA), the National Imagery and Mapping Agency (NIMA) and the German (DLR) and Italian (ASI)space agencies. It is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Earth Science Enterprise, Washington, DC. Size: 149 by 40 kilometers (92 by 25 miles) Location: 16.9 deg.

Oil Slicks, Gulf of Aden
Title Oil Slicks, Gulf of Aden
Description In this view of the Gulf of Aden, and the coast of north Yemen (13.5N, 48.0E) the sunglint pattern clearly delineates oil on the water surface as bright streaks relative to the surrounding water. The oil is most likely the result of oil tanker ships flushing their tanks as they transit the gulf. Once formed, the oil slicks are pushed around by the combined effects of wind and currents as can be seen in the deformations of the long offshore oil streak.

Wadi Habawnah, Saudi Arabia
Title Wadi Habawnah, Saudi Arabia
Description These unique weathered volcanic intrusions near Wadi Habawnah, Saudi Arabia (18.0N, 44.0E) are located near Najran, north of the Yemen border. This harsh and rugged desert landscape has been heavily wind eroded and, to a lesser extent, water eroded, as evidenced by the dendritic patterns in this region where rainfall is a seldom occurance. Only a dwindling number of nomadic tribes inhabit this harsh region of few resources.
